Provided is a method for preventing an accident related to children or pets that may occur by a home appliance using artificial intelligence. According to the present disclosure, the method for preventing the accident comprises comparing a distance between the home appliance and a generation position of the voice signal and a reference distance when the generation position of the voice signal is outside of the home appliance. Then, the present disclosure enables switching a door of the home appliance to a lock state when a distance between the home appliance and the generation position of the voice signal is less than the reference distance. Thus, the present disclosure may enable controlling the home appliance to prevent children or pets from entering an inside of the home appliance.
